Workaround

The timeout for locking database tables in older versions of the NuGet plugin was very brief. Under high load performing updates to Nuget packages, this results in lock contention. Newer versions have the timeout set to 60 seconds by default. As a short term workaround, you can also set this to 60 seconds without upgrading Nexus versions.

Note:It is strongly recommended to always use the latest Nexus version when using NuGet features since NuGet is a fast moving project that has been known to introduce bugs into otherwise working Nexus installations.
